【摘要】 <正> 塔里木盆地中的塔克拉玛干沙漠是我国面积最大的沙漠。盆地南部的沙漠南缘及深入沙漠腹地的河流下游的一些地方,“丝绸之路”南道通过这一带,历史上曾一度繁荣。其后受各种因素的作用,城郭、田野被流沙所埋,在原来平坦的地面上,形成沙丘连绵的景象。丰富的历史遗迹和文献记载为研究该地区历史时期的沙漠化提供了方便。 研究这一地区沙漠化的历史情况,将为今后利用当地的水土植物等资源及预测可能引起的某些环境退化问题,俾益借鉴。在生产实践和科学上有一定的意义。更多还原

【Abstract】 The Southern Part of Tarim Basin is the area Where the south route of Silk Road got through. In ancient times, this area once had been quite Prosperous, but late it deteriorated to desertified lands, which resuited from the special local natural conditions (such as the extreme conditions of dry climate, the widespread and loose deposition, the removal of rivers and so on) and social factors(such as chaos and wars, etc). The processes of desertif ication were developing quickly during-the Han-Jin Dynasty, the Tang Dynasty (especially in the later period), the song Dynasty and Yuan Dynasty.更多还原
